Machine tools are main components in many industries, especially manufacturing and automotive industries. Some of the most widely used machine tools are lathe, drilling machine, grinding machine and milling machine. These machines are not only used in industry, but also used for education and workshop. These machines are generally designed at a grade with certain dimensions and precision If the working volume or the dimensions of a machine tool are changed, then a new design must be created with a particular precision. This process is relatively inefficient because it needs much time to know the exact precision of the new design. In this study, parametric concept in design creation is used to overcome this problem. <br /> <br /> The application of parametric concept on vertical CNC milling machine is used to change the dimension of each component by simply changing the working volume while the precision level is kept constant. This can be done because every component in the machine is interconnected. The parametric concept in this machine is used to design a platform of table. This process begins with application on the block table (not using T-slots, linear guideways and ballscrew stands using ordinary comparison, not according to standard). Further, it is applied on vertical CNC milling machine table platform (using standard t-slots, linear guideways and ballscrew). <br /> <br /> Parametric concept on vertical CNC milling machine table platform is used to determine the change in the dimensions of the table (length, width, and height) relative to the change in working volume (length, width, and height) in a condition with constant precision level (maximum deformation is kept constant) of 1.69 um on the block table and 1.75 um on the vertical CNC milling machine table. In a constant precision level, the increase of the height of the table for a change in working volume from minimum (500mm x 500mm x 400mm) to maximum (1000mm x 1000mm x 800mm) is 5.5 times of the minimum height for block table and 5 times for vertical CNC milling machine table.
